WILLIAM F. AIDLO'ITE, OF HIATTVIL LE KANSAS, A-SSIG-N OR OF ONE-HALF TOEARL WILLIAMS, 0F I-IIATTVILLE, KANSAS.

SICKLE-IBAR.

To all whom it may concern:

Be it known that I, WILLIAM F. AmLoTTE, a citizen of the United States,residing at Hiattville, in the county of Bourbon, State of Kansas,haveinvented certain new and useful Improvements in Sickle-Bars, of whichthe following is a full and exact specification.

The present invention relates to improvements in sickle bar constructionfor mowing machines, and one object of the invention is to provide animproved sectional knife bar construction which will efiect economy inrepair cost by permitting the' renewal of defective or broken partswithout incurring the delay, trouble and expense incident to repairing acontinuous bar by the process of welding or the like.

To this end a novel sectional sickle bar construction has been devised,with the parts so arranged that on the appearance of a fracture or otherdefect, the defective part may be quickly removed and a new part placedin position with but very little delay.

It is a further object to provide a neat, simple and compactconstruction for the desired purpose, and of an inexpensive nature andrequiring no change in the remaining portions of the machine.

lNith these general objects in View, the invention will now be describedwith refer ence to the accompanying drawing illustrating one form ofconstruction which has been devised. for embodying the improvements,after which those features and combinations deemed to be novel will beseverally set forth and defined in the appended claim.

In the drawing- Figure 1 is a plan view, partly broken away,illustrating a sickle bar constructed in accordance with thepresentinvention;

Fig. 2 is an edge view of the same;

Fig. 3 is an edge view of a portion of the sickle bar on a larger scale;

Fig. 4 is a plan view of the lower face of the same portion of the bar;and

Fig. 5 is a transverse sectional view of the sickle bar.

Referring-to the drawing in detail, this illustrates the improvements asembodied in a sickle bar comprising the series of bar sections 2arranged in alinement and 1n abutting relation, the combined length ofthe sections being that required to accommodate the desired number ofknife blades Specification of Letters Patent.

joint with the corresponding bar sections,

and suitable fastening means, as the rivets 6, are employed for unitingthe parts in this relation.

For further securing the parts together in rigid form a series of platemembers 8 may be applied to each joint on the under faces of the barsections and the intermediate rivets 6 of the corresponding knifebladesused for fastening said plate members in position as illustrated. Theseintermediate pairs of rivets 6 may be countersunk if desired, andpreferably are so countersunk with reference to the plate mem bers 8 andthe latter beveled as shown, so that when the sickle bar is assembled inoperative position upon the finger bar 10, proper clearance will beafforded for accommodating the plate members 8 and their rivets withinthe channel 12 of the finger guards 14.

At the head of the sickle bar the rivets 6 may be utilized also forsecuring the head member 16 to which the usual pitman connection is madefor operating the cutter.

In case of-a broken, worn, or defective part, all that is necessary isto remove the portion which requires to be repaired or renewed, and thismay be accomplished by cutting the appropriate rivets and taking out thepart in question. The rivets may obviously be readily sheared by simplysupporting the sectional bar and delivering a few sharp blows with ahammer upon the head of the blade that is secured by the particularrivets to be cut. The renewal or repair of parts may then be quicklymade and the same riveted back in place in the relation shown anddescribed. The expensive and troublesome task of removing a number ofknife blades for the purpose of welding a continuous cutter bar, whenbroken, is obviated, as well as the time required to take the bar to ashop for making a repair of that nature. With the improved sectional barconstruction, any needed repairs may be quickly made and attended toright on the ground at a minimum of expense and trouble.

"that aneat, simple and efficient construction has been devised forfulfilling the objects of the invention, and While What is now deemed toconstitute the preferred form of embodiment of the invention has beendescribed andillustrated, the right is reserved to such formal changesand modifications as may fairly fall Within the scope of the followingclaim.
